You have a dead short to ground. Check your pin outs on the din plug. Did you try the changer before plugging into the radio? and, is the changer designed to go with that radio?....Sometimes the people that design this stuff place a diode across the positive power in the ciruit to ground(negative) as protection for cross polarity in connection. If this diode shorts it can cause your problem or if the polarity is wrong....Good-luck
